Recorded a year before their legendary Fillmore shows, this documents the Brothers' stand at a Cincinnati psychedelic ballroom of the period, ("We're going to have some electric wine," Gregg Allman comments at the end of the first set), and it's very much Gregg and Duane Allman's show. At this point, second guitarist Dickie Betts played mostly rhythm, sang hardly at all, and had yet to provide the country influence on their sound that would culminate in the signature "Rambling Man."

The Allmans heard here are (merely) a brilliant blues band; if you need proof, check out their world-class version of "Hootchie Cootchie Man." As for the rest, Duane's slide guitar is as fiery and otherworldly as you'd expect throughout, and Gregg' vocals are both impassioned and subtle.
